A highly directional microphone assembly. It operates by placing an omnidirectional microphone capsule at the focal point of a parabola. Parabolic microphones are most effective at mid- to high-frequencies.

A parabolic microphone is a microphone that uses a parabolic reflector to collect and focus sound waves onto a receiver, in much the same way that a parabolic antenna (e.g., satellite dish) does with radio waves. Typical uses of this microphone, which has unusually focused front sensitivity and can pick up sounds from many meters away, include nature recording, field audio for sports broadcasting, eavesdropping, law enforcement, and even espionage.
